Support extra PXE kernel arguments for Inspector

Browse Source 
As an operator I want to be able to specify additional kernel arguments
for nodes being inspected by ironic inspector so that I can pass
arguments to Ironic Python Agent (IPA).

A number of optional features in IPA are configured via kernel command
line arguments, e.g. ipa-collect-lldp.

This change allows additional kernel arguments to be provided for use
by the IPA ramdisk during inspection.

Allows additional kernel arguments to be specified in inspector PXE config.
A number of optional features in the Ironic Python Agent (IPA) are
configured via kernel command line arguments, e.g. ``ipa-collect-lldp``.
It is now possible to specify additional kernel arguments for use by the
IPA ramdisk during inspection with the ``inspector_extra_kernel_options``
variable.
